Sprinkler Blowouts & Winterization in Spokane, WA
A sprinkler blowout uses compressed air to push the water out of your irrigation lines, valves and heads so there's nothing left to freeze. Automated Lawn & Pest Control blows out and winterizes residential and commercial sprinkler systems across Spokane and Coeur d'Alene every fall, before the first hard freeze can crack pipes, valves or the backflow preventer.

How it works
How a Sprinkler Blowout Works
Shutting the water off isn't enough: water still sits in the pipes, valves and low spots of the system. A blowout clears it zone by zone.
-
Water supply off
The irrigation water supply is shut off so no new water enters the system.
-
Air through each zone
A compressor is connected and each zone is run one at a time, pushing the water out through the heads.
-
Run until dry
Each zone runs until the heads spray air and mist instead of water, then it's on to the next one.
-
Ready for winter
With the lines, valves and heads empty, there's no standing water left to freeze and crack over the winter.
When to book
Before the First Hard Freeze
Blow out your sprinklers in the fall, once you're done watering and before the first hard freeze. In the Spokane area that usually means October.
Fall is the busiest stretch of the year for sprinkler crews, and the weather doesn't always wait. After one early cold snap, our owner summed it up in a reply to a customer: “Glad we got things shut down before we had another early winter!”
Getting on the schedule early is the easiest way to avoid racing the forecast. If something needs attention when we come out, like a sticky valve or a broken head, we'll tell you what we found, and our sprinkler repair team can fix it before spring.

Questions
Sprinkler Blowout Questions
When should I blow out my sprinklers in Spokane?
In the fall, after your last watering and before the first hard freeze. In the Spokane area that usually means October. Book early: fall is the busiest time of year for sprinkler blowouts, and an early cold snap can arrive before you expect it.
Why do sprinklers need to be blown out?
Water left in an irrigation system expands when it freezes. That can crack pipes, fittings, valves and the backflow preventer, which means leaks and repairs when you turn the system back on in spring. A blowout clears the water out before it can freeze.
Isn't shutting off the water enough?
No. Shutting off the supply stops new water from coming in, but the water already in the pipes, valves, heads and low spots stays there. A blowout uses compressed air to push that water out, one zone at a time.
Do you winterize commercial sprinkler systems?
Yes. Automated Lawn & Pest Control blows out and winterizes both residential and commercial irrigation systems in Spokane, Spokane Valley and Coeur d'Alene. See our commercial property services.
What if you find a problem during the blowout?
We'll tell you what we found, like a stuck valve or a broken head, and our sprinkler repair team can fix it so the system is ready when you turn it back on in spring.
How soon can you come out?
It depends on the week, and fall is busy. We try to schedule enough staff and equipment to stay flexible, so call (509) 818-1831 or request a quote and we'll give you a real date.
